Several pieces in Eskell’s new spring collection, which just debuted on the local line’s site, highlight that under-the-radar erogenous zone—the back. Offering just a peep, the designers’ take on the look is sexy and wearable for most—a punishing gym regimen is not required. Notable pieces include a proper-looking red shirtdress that billows invitingly at the back and a sweet spring top with an unexpected horizontal slash. The collection is available online and at the Eskell boutique, 1509 N. Milwaukee, 773-486-0830.
